CONNECT RIMS TO RF SOURCE(S)

For each RIMe — connect the external RF source to the

corresponding RIMe (service specific) simplex or duplex

QMA connectors. See Figure 7.

RIX TO OIX CONNECTIONS

Note: Each RIX module can be connected to two OIUs.

Using the appropriate length ERFC cable (according to distance

of available OIX port), connect the HEU RIX module 9-Pin

connector to the corresponding connector on the OIU OIX

module. See Figure 8.

Refer to Section 11 for schematic diagram of coax connections

in a maximum HEU-OIU configuration of 4x4 where all HEU

units are connected to all OIU units.

RIX PILOT CLOCK CONNECTIONS

The pilot clock connections are required in both single- and

multiple-chassis configurations. Referring to Figures 9, 10, and

11, use the QMA/QMA jumper cable (PCKC47 provided with

each RIX) to connect the REF OUT and REF IN ports of each of

the RIXs in the HEU chassis.

Notes:

• The REF IN and REF OUT pilot clock ports must be

connected in a closed loop as shown in Figure 10.

• Both RIX modules of each chassis must be

connected.
